We typically don't beat teams that Kubiak believes we can't "settle for FG's" against. EX: Peyton's Colts, Rodgers, Brady, Brees. When Kubiak feels like he has to be aggressive in his playcalling we make bad decisions.

Kubiak is 1-1 against Rodgers and Brees.
He's 1-2 against Brady, but the team he took over was in rebuilding mode.
We lost a bunch to Manning for the same reason (several games were close).

This system has been proven with the Broncos for a long time, and now here.

With a top 10 defense it brings competitive (play-off contending) years in and years out.
